Actinopteri (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Linophrynidae
Etymology: Linophryne: Greek, 'linon' = flax or anything made of flax such as "cord," "rope," or a "net" + Greek, 'phryne' = "toad" (refers to a toadlike fish that fishes with a net) (Ref. 86949). More on authors: Regan & Trewavas.

Morphology | Morphometrics
soft rays: 3. Metamorphosed females distinguished by the following characteristics: escal bulb without distal prolongation; single distal filament and series of about 10 branched filaments on each side; absence of anterior escal appendage; total length of barbel 25-33% SL, distal part with series of 5 photophores, proximal photophores set on short stalks; dense concentration of subdermal melanophores on caudal peduncle (Ref. 86949).
Also mesopelagic (Ref. 10762).
